Three girls are being held in connection with a pair of South Loop pepper spray attacks Wednesday night that left two women injured.

In the first attack, a 16-year-old girl is accused of spraying a 24-year-old woman with pepper spray while two other girls, 14 and 17, blocked her escape. That happened about 10:30 p.m. in the 1100 block of South State Street.

About 10 minutes later, police said the 17-year-old sprayed a 26-year-old woman in the 1300 block of South State Street. Like in the first attack, the other two girls blocked the 26-year-old's escape, police said.

It's not clear what prompted the attacks. The 24-year-old was taken to an area hospital and treated for her wounds and the 26-year-old had her eyes flushed with water near where she was attacked, police said.

Police said the three attackers will likely be charged as juveniles. Check back for more information.
